On deformation spaces of quadratic rational maps
arXiv:1606.00723 · doi:10.1093/imrn/rnab320
Abstract
We study the group of self-equivalences of a partially postcritically finite branched cover and answer a question of Adam Epstein about contractibility of certain deformation spaces of rational maps.
Section 7 on connection with postcritically finite maps and Appendix with classification of equalizing multicurves for Per'4 were added
